Who knew Reese Witherspoon had such an adorable big brother?

Or that she even had a brother

Reese Witherspoon is full of surprises, isn't she? The actress posted a photo of herself with her older brother, John, on Instagram, reminding us all that she's not the only Witherspoon out there.

This is so typical. We're always the last ones to know everything! Reese Witherspoon is notoriously private about her life, but how did we not know she had a brother? OK, we knew she had a brother, but photos of these two together are rarer than snapshots of Big Foot grocery shopping…

Luckily Witherspoon shared a photo of her older brother, John Jr., on Instagram, with the caption: "Love seeing my brother. He shares my love for doughnuts and that's how I know we are related." So adorable, we can barely handle it!

Anybody else spot the similarities between these siblings? They are definitely Witherspoons — the force is strong with this family. These two are just doing normal brother-sister things, like grabbing doughnuts and sipping from mugs with "Nashville" written across them. It's just so sweet, and we're very glad Witherspoon shared the moment with the rest of the world. It just proves that she is indeed the most precious human being in the universe.
